VALVE FULLER Filed Feb. 29, 1932 '3 Sheets-Sheet 3 INVENTOR fi'tBYCi v (QurM ATTORNEYS Patented July 18, 1933 .ROY o. WILLIAMS, or WAYNE, OHIO VALVE FULLER Application filed February 29, 1932. Serial No. 595,855.

The primaryobject of the invention is to decrease the amount of labor and expense in replacement of parts of the valves when they become worn or damaged.

The invention relates to a valve pulling device, the general object of'the invention being to so arrange and construct the parts thereof that the two valves in a well may be connected or disconnected in the well at 1L1 theoption of the operator on the surface of the ground above by means of turningthe rods either to the right or to the left.

Another object of the invention is to provide means whereby the thread on the bolt,

. 113 tap, or connectingdevice is protected against injury from any heavy blows on account of the two valvesst'riking together either from design or accident, also to afford means whereby the casing, collar shield or nut is 23 held in proper'position, and means to hold said casing, collar shield or nut from becoming disconnected. 1

Another feature of the invention is that it can be used on either valve, so that it is not necessary to pull the lower valve in order to arrange the parts.

This invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fullydescribed as illustrated in the accompanying drawings and specifically pointed out in the appended claims.

In describing the invention in detail, reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several Views and in which;

The device which I shall hereafter refer" to in its completeness as a valve puller, is an assembly of six different parts, five partsassembled in connection with the lower valve, 7o thefsixth part being a reconstruction of-the lower part of the upper valve.

1 indicates a casing of steel or other suitable material, 2 indicates a housing in which the thread of the tap, bolt or'connecting link is protected. This housing is made of brass, bronze, or other suitable non-corrodible material. The casing and housing are forced together by pressure or other means to hold them firmly together.

In referring to the casing and housing combined I will refer to them asone unitrepresented by 3 and designated asa shield.

4 represents a tap, bolt or connecting device and is held in position in the valve cage by means of a nut 6 within the cage, and" above by means of a spring 5 between the. cage and the housing of the shield. This 'unit will hereafter be referred to as a tap.

5 indicates the spring and is usedto hold the device up against the top of the cage 8 i so as notto interfere with the working of the'ball of the lower valve. It is made of bronze or other suitable noncorridible material. It is made of suitable size and length so that whenthe rods above are lowered and upper valve bottom teeth 11, (Figure 5) en gage with shield 3, the weight of the rods above shield 3 rests on the lower cage 8. The casing 1 is of sufficient length below the hous- 10G illustrated in ing 2 to allow the compression of the spring within the casing, so that the lower portion of the shield 3 rests upon the top of cage 8.

6 represents a nut which connects'the tap 4. and cage 8. It should be of such design as to furnish the maximum amount of strength yet small enough to be inserted through the bottom of cage 8 and extend into the opening of cage 8. There should also be a key 7 or other means of securing the nut to tap 4.- after it has been connected with tap 4 by means of threads 9 and 10. After all parts have been assembled and properly connected to the valve cage 8 and-placed in the well, and when it becomes necessary to replace or renew the valves, the coupling is accomplished by means oflowering the rods with valve bottom teethvll engaging with teeth 12 of shield 3. The weight of the rods above holds the two members in mesh. The operator turns the rods to the right about nine times. The shield being firmly gripped by member 11, turns with the rods above. On account of tap 4 being firmly held in cage 8 by means of nut 6, the thread on tap l is forced out of shield 3 and into engagementwith the thread of the upper, valve bottom 15, connecting the two valves together.

A shoulder 13 in the housing 2 and a shoulder 14 on tap 4 prevents shield 3 from becomingdisconnected. A keyor cotter-pin 7 throughv nut 6 and tap at prevents nut 6 from unscrewing when separating the valves. As Figure 9 the shield' 3 having pointed teeth 12 is able to grip anysjtanding valve-cage, so it isnot necessary to pull the lower valve in order to arrange the device when'such valves are not needing repair. To arrange the device so that both valves may be raised at thenext time of pulling, it is only necessary to attach'the device to a cage on the bottom of the upper valve. The device is the same, only the spring may be transferred to the inside of the cage.

When using the. device on the lower valve bottom, further changes may be made to ar-s range the device in a more compact and lighter formas illustrated in Figs. 10 and 12.

From the foregoing description taken in connection with the accompanying drawings, the construction and operation of the invention will be readily understood without requiring a more extended explanation.

It is understood that changes may be made in the construction and in the combination and arrangements of the several parts, without departing from the scope of the appended claims. H

I. am aware of the fact that; prior to my invention, valve pullers have ing a tap, bolt or connecting device together with a nut, shield or protector. I therefore do not claim such a combination broadly.

I claim as my invention: j

1 valve bottom being threaded 'rocatory been'made us a recess deep enough to 1. In combination, a standing valve cage, a traveling valve bottom, a threaded tap operable by rotation of the traveling valve bottom to connect the latter with the standing valve cage, and means to relieve the threads of the weight of the rods when imposed upon the traveling valve bottom, as the latter is rotated. I

2. In combination, a standing valve cage, a threaded tap reciprocably mounted therein and projecting upwardly, a spring urging said tap to its uppermost position, a shield threaded to lit said tap, a traveling valve bottom similarly threaded, and means for causing said traveling valve bottom and shield to rotate in unison, said shield being engageable with the standing valve cage, upon partial compression of the spring to relieve the threads of the weight of the load imposed upon the traveling valve bottom.

3. In combination, a standing valve cage, a threadedt'ap reciprocably connected there with, a traveling valvebottom, a threaded shield normally covering the tap threads, a spring urging said shield and tap upwardly, said shield constituting spacing means between the standing valve cage and the traveling valve bottom to take the load imposed by the weight of the'rods and to relieve the threads of such weight, said traveling valve bottom being threaded to receive the tap, and means for connecting the traveling valve bottom'to said shield to rotate the latter by a rotation of said valve bottom whereby the tap is screwed partially from the shield into said valve bottom.

l. In combination, a standing valve cage, a threaded tap connected for limited reciprocatory movement with respect to said cage, a shield threaded to lit the tap and normally covering the tap threads, a spring urging said shield and tap upwardly, a traveling valve bottom adapted to engage the shield, said shield constituting spacing means between the standing valve cage and said valve bottom to prevent the load on said valve bottom from being imposed on the threads, said to receive the tap, and inter-engaging teeth on the shield and said valve bottom for transmitting rotational movement of said valve bottom in either direction to the shield, whereby the tap may be screwed from the shield into said valve bottom or vice versa.

5. In combination, a standing valve cage, a threaded tap connected for limited recipmovement with respect to said cage, a shield threaded to fit the tap and normally covering the tap threads, a coil spring urging said shield and tap upwardly from the standing valve cage, said shield being formed with receive the spring when compressed, a traveling valve bottom adapted to engage the shield, said shield constitutingspacing means between the standvalve cage having threads to receive the tap, a shield threaded on the tap and normally covering the tap threads and constituting spacing means for supporting the traveling valve bottom and its load from the standing valve cage without imposing the load on the tap threads, and means for keying said shield to the standing valve cage, whereby rotation of the traveling valve bottom and tap will thread the latter into said standing valve cage to connect the two valve cages.
